Google Co-Op : Roll Your Own Custom Search Engine

I may be way behind the times on this one, but Google has a yet another beta product called Google Co-Op which lets you create your own Custom Search Engine (CSE) that only searches the site(s) you specify.

You can even market your CSE and get paid for the ad revenue it generates. That's actually how I became aware of the CSE, today Charlie Arehart blogged about ColdFusion specific CSEs that have been setup.

Not limiting results only to your selected sites, but just emphasizing your selected sites in the results.

Excluding sites or specific pages

The excluding feature has me a little bit excited, as it would be pretty cool to create an exact mirror of Google, but then start excluding sites that you find are completely worthless. I am not completely sure if this is even possible, but it would be hella cool.
